INTERVENTIONAL RADIOLOGY WITH LASER IN BONE AND JOINT - 09/09/11
Résumé |
Lasers are used extensively in many surgical and medical specialties. The word laser is an acronym for light amplification by stimulated emission of radiation. The laser is able to cut, coagulate, and vaporize tissue. Lasers are intense light sources and they use photons and light energy to produce their tissue effect. Normal light sources produce white light of many different wavelengths propagating in many different directions. The light emitted by lasers has three unique qualities:
• | All waves are of the same wavelength (monochromatic) |
• | The waves are in phase with each other (coherent) |
• | The waves are exactly parallel to each other (collimated) |
These properties enable reliable and direct transmission of high amounts of energy over long distances.41
Laser energy, with its powerful and precise ability to ablate, coagulate, and vaporize dense tissues as well as its transmissibility in optical fiber, makes this an ideal tool for use in musculoskeletal surgery. Arthroscopic laser surgery is used clinically in the treatment of joint disorders, particularly for cartilage ablation and restoration. The laser is also used in polymethylmethacrylate removal.1, 37
Percutaneous laser disc decompression (PLDD) and interstitial laser photocoagulation (ILP) of bone tumors are typical applications of laser in musculoskeletal interventional radiology.17, 18 This article reports our experience performing 169 PLDDs and 28 ILPs of osteoid osteomas.
